Math Problem Statement
Solution
The image contains a question with two inequalities, asking to determine their solution sets:
-
Inequality (a):
We will solve this inequality step-by-step:
Combine like terms: Add to both sides: Combine like terms: Add 12 to both sides: Divide by 5: So, the solution to inequality (a) is . This means all numbers greater than are solutions.
-
Inequality (b):
Distribute on the left side: Add to both sides: Subtract 12 from both sides: Divide by 4: So, the solution to inequality (b) is . This means all numbers less than or equal to 0 are solutions.
Answers:
- For (a):
- For (b):
Would you like more details on the solution steps? Here are some questions you might want to consider:
- How do we handle inequalities involving both sides with variables?
- What happens if we divide or multiply both sides of an inequality by a negative number?
- Can you always combine like terms in inequalities in the same way as equations?
- What is the importance of checking the solution in inequalities?
- How would the solutions change if the inequalities had a different sign (e.g., instead of )?
Tip: Always double-check the direction of your inequality sign when multiplying or dividing by a negative number!
